UMBRELLA.

.QPECIPIC'ATION forming part of Letters Patent N0. 355,142, dated December 28, 1886.

Application filed Jnne 28, 1886. Serie! Ne. 206,417. (N model.)

T0 aZZ whom it may concerni Be it known that I, THOMAS ALBEN GRAB- TREE, a citizen 0f the United States, and a resident of Bast Surry, in the county 0f Hancoek and State 0f Meine, have invented cettain new anti useful Improvernents in Um brellas; and I hereby declare that the following 1's a ful], clear, and exact description of the in vention, which willenable others skilled in the art t0 which it appertains 130 make and nse the sa1ne, refere1 1ce being had to the ccompanying drawings, which form a part 0f this specification, and in whieh- Figure 1 js a perspective view 0f as much 0f an umbre1la 2LS Will show my improvement. Fig. 2 is a sin'1i1ar view 0n an enlarged scale, showing the improvement in position when the n mbrella is folded; and Fig. 3 is a perspective view 0f the patrts of the improvement detached.

Similar 1e tters of reference indicate eorresponding parts in all the fignres.

My invention h2bS relation to slides for um b rellas; and it consists in the improved coustruction and combinzttion 0f parts '0f such a s1ide, having a bayonet-slot et the npper and lower end l'0r engagingstuds at the upper and lower portions of the umbrella-staft, es hereinafter m0 re fu1ly described 2tlld claimed.

In the aecompanying drawings, the letterA indicates the staff of the umbrella, which statt may be 0f any suitable materia], 2tnd may have any suitable 0r11amentation, 2LII. which is formed with two .studs, B and O, respective1y at the upper ztnd lower portions of the staff, the ortion nearest the handle being in this case referred t0 as the lower end. Sliding upon the stuft" between the studs B 2tnd 0 is a runner, D, the ends of which are provided with the outwardly-flztring notches E E, each notch having a laterally-extending recess, F, at its base. An outer sleeve, H, is seeured upon the rnnner by means of a pin, L, near thelower end of the rnnner, which pro- 5 jects th'r0ugh the slot K near the lower end 0f the outer sleeve, seid s1ot being shorter than the mouth or Guter portion bf the notches E. An ordihary notch, M, is seeured t0 the upper end of the sleeve H. At the lower end of the 50 runner is a mi1led fing, G, for the purpose of securing a firm hold of the runner, when it is de sired t0 tnrn the same on the shaft. As the hotch is held from tnrning around the rl1nner by the ribs and byaces, which are secured to' the crown-notch by the nsual manner, it will be Seen that the runner D can be readily tnrned aronnd the staft withi'n the limits of the sl0t K, the sleeve II aft'ording as long a bra0e 0x stay for the notch M as is fonnd in the runners used upon the ordinary umbrellas.

When it 1's desired t0 reise thenmbrella, the runner D is turned around the staft unti1 the recess F is disengaged fr0m the 10wer pin, G, whenit'can be pushed up the staff until the upper pin, B, enters t-he upper notch, E, when a slight turn of the 11'1nner causes the upper recess, F, to engage with the pin B, which prevents therunner from sliding down the staff. Te c1ose the umbrella,the above process is reversed.

Previous to my invention.umbrelladnnners have been made with ashallov'vgroove 0r channel around them, in which asleeve having the notch-piece around it has been secured; but this method is objectionable, as the only support for the entire weight of the top is the' lower side of the shallow groove, which would soon wea-r suffieiently to permit the sleeve t0 s1ip down 0ver the rnn.ner. Another objection t0 it is the difficulty 0f fitting the sleeve in such agroove; hence I do not wish to claim such a construction; but

What I- have invented, and desire 130 secure by Letters Patent, is

The combination, with a runner fornmbrellas, having a recess at the base of an Outwardly-flaring notch at each end, of apin projecting fr0m its intermediate portion and a mi1led ring around its lower 0rti0n, and an outer s1eeve around seid runn6r having a notch around its upper portion and a slot near 1't-s lower portion.

In teStirnony that I c1aim the foregoing as m'y own I have hereunto affixed my signatnre in presence 0f two witnesses.
